fuse question

[lawaco12]

I think that I have read before that on chevy or gmc that there is a fuse under the hood that you have to move a position to enable your tow vehicle to charge your battery on 5th wheel camper. Does anyone have any infromation on this. Thanks in davance

It's more like you have to add a fuse to an empty space or hook up a wire that already exists. What make, model and trim line are you dealing with?
For my 2001 Suburban there is a fuse under the hood for that. But you wouldn't know it unless you looked in the owners manual as it's labeled Stud#2.
